Geological disaster crack measuring device

Abstract

The invention belongs to the technical field of geological disaster measuring tools, and particularly relates to a geological disaster crack measuring device which comprises a connecting base body, a base is fixedly mounted on the lower surface of the connecting base body, a first notch is formed in the lower surface of the base, an annular sliding groove is formed in the outer circumferential surface of the base, and a sliding base table is slidably mounted in the annular sliding groove. Meanwhile, a laser swinger can be matched to compare and record an included angle between sinking or rising of an area with cracks and the horizontal plane, azimuth scales can be additionally arranged on the surface of the base to be used for measuring the surface cracks in a matched mode, and after measurement is completed, the movable connecting arm is lifted upwards and reset; therefore, rapid measurement of geological disaster cracks is realized, and the measuring tool can be used for measuring irregular cracks of the geological disaster cracks and inclination angles of rising and falling of the earth surface relative to the earth surface, so that the problem that an existing geological disaster crack measuring tool does not have measuring and using characteristics is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of geological disaster measuring instruments, and in particular relates to a geological disaster crack measuring device. Background technique [0002] Geological disasters refer to geological processes or geological phenomena that are formed under the action of natural or human factors and cause losses to human life and property and damage to the environment. The distribution and change of geological disasters in time and space are subject to natural The environment is also related to human activities, formed under the action of natural or human factors, and causes damage and loss to human life, property and the environment, such as ground fissures and collapses. [0003] Ground fissures are one of the more common geological disasters in geological disasters. Ground fissures of tectonic origin are often in the form of multi-level echelon combination on the surface. Some of the ground fissures are related to ...

Problems solved by technology

[0003] Ground fissures are one of the more common geological disasters in geological disasters. The ground fissures of tectonic origin are often in the form of multi-level echelon combination on the surface. Some of the ground fissures are related to seismic activity; It is related to underground mining activities, etc. At present, it is necessary to measure and record the cracks that appear in the ground. However, the traditional measurement tools used are more versatile, but there are obvious problems of poor pertinence when measuring surface cracks.
